摘要：
Based on analysis of the Corrosion prestressed concrete beam with finite element model, the paper presents the mechanical performance of concrete beams in different corrosion rates. When the corrosion rate is less than 5%, the strand corrosion has little impact on the load capacity. With the increase of the corrosion rate more than 5%, what damage happened to Beam is little steel damage and brittle damage even without apparent warning and at the same time the Corrosion of steel strand will cause the decrease of the ultimate load capacity with the deterioration of ductility.
